Niloak Art Pottery
Niloak is koalin spelled backwards. It was produced in Benton, Arkansas, USA by the Niloak Company from 1909 until 1946. They h ad transitioned into contract work for the military during World War II. When those contracts ended they made an effort to resume production of their pre-war pottery, without much success. At that point they transitioned into a tile company with some success.
In their early years they produced, and patented, a type of pottery they called Missionware. Their process blended different color clays with shapes that went well with the Mission Style of the then popular Arts & Crafts movement. Missionware looks really nice sitting on a fumed oak Stickley product.
Missionware is enjoying a resurgence in popularity and prices have risen accordingly. In fact, there is little or no interest in their other art pottery.
